I just picked up a Gutwire grounding cable and plugged it into one of the open RCA inputs and plugged it into the electrical socket. I was nearly stunned at the increased clarity, focus and nuanced detail this brought to my system. This was one helluva upgrade that did not cost an arm and a leg.
I fully agree. A no brainer everyone should try for themselves.
I'm using a grounding router with a separate grounding wire to every piece of equipment.
I went even further and grounded the tv stand and every speaker driver (frames and magnets).. Considering the movement within every speaker it's not unexpected the improvement is as great as earthing equipment.
All I can say is well worth the effort. If there's no improvement, I'd be most surprised.
